燃炭을 燃燒시킬 때 흙통중에서 一定量의 煉炭을 一定時間 燃燒를 持續시키기 위하여 空氣의 供給을 制限하게 되므로 많은 量의 一酸化炭素가 發生한다. 그러므로 一酸化炭素의 發生을 抑制하는 基本實驗으로 窒素, 酸素 및 一酸化炭素의 混合가스 및 炭素의 存在下에서 一酸化炭素의 燃燒率을 測定한 結果 一酸化炭素 燃燒溫度는 $700^{\circ}C$以上이고 空氣의 供給이 增加 할수록 一酸化炭素의 燃燒率이 改善됨을 알았다. 이러한 事實에서 燃燒時間의 延長과 一酸化炭素의 發生 抑制는 서로 相反되므로 두 가지 條件을 滿足시키는, 보다 效果的 燃燒裝置를 考案하였다. 즉 內徑이 다른 二重鐵筒으로 暖爐를 만들어 若干의 二次空氣가 에어자켓 下部에서 들어가 上部의 작은 구멍에서 나오게끔 하면 燃燒中인 煉炭과 熱交換되어 燃燒雰圍氣의 溫度는 低下된다. 따라서 燃燒時間은 길어지면 또 二重鐵筒을 通하여 上昇하는 豫熱空氣는 一酸化炭素의 再演燒를 促進시키게 되므로 一酸化炭素의 發生量은 흙통을 使用하였을때 보다도 1/20 程度로 減少된다.

In the course of anthracite briquet combustion, air draft is usually controlled to continue burning of definite amount of briquet in the conventional hollow clay cylinder with air inlet hole open for given time, so that a large amount of CO tends to be produced. Therefore, it is necessary to establish an improved combustion process to depress the yielding rate of CO and for this purpose, we performed a basic experiment in which combustion rate of CO was measured in the mixture of $N_2, O_2 $and CO gas with or without the presence charcoal at the various temperature. The observed results showed that the burning temperature of CO is about 680${\sim}700^{\circ}C$, further burning rate of it was increased with increasing the amount of draft. From these facts, longer combustion time and low CO generation are thus contradictory to each other and it has been long desired to make those two compatible somehow. The purpose of the present investigation lies in designing an effective new briquet stove to meet the above requirements. The essential feature of the new briquet stove consisted in the use of two hollow iron cylinders with different inside diameter. A cylindrical air jacket thus formed served as a path through which small amount of secondary air run from the bottom of the stove to the upper vent holes. Heat exchange occurred between the upgoing secondary air and the burning briquet, which lowered the combustion temperature of the briquet. The results observed were selfevident as anticipated. It was confirmed that the combustion time was increased tolerably due to the heat loss from the combustion zone and that CO in the flue gas was reoxidized at the upper portion of the stove by the upgoing hot secondary air. By this reoxidation reaction the concentration of CO in the flue gas was found to be about 1/20 of that in case the conventional clay cylinder was used as briquet jacket.
